Default air boat wieght

Can an air boat be too light.
I was wacthing the dicovery channel last night and they had some stuff that is the lightest material on earth. It was on the show that came on after myth busters.
Not sure how much money it costs for this stuff or even how strong it is to put up with the abuse.
I have ni idea what this stuff was called.

Yes, an airboat can absolutely be too light. Flatbottom hulls are especially prone to this because of the large surface area of the bottom of the hull if the boat becomes airborne. You have to find the balance of weight and power. Of course it's always easier to add weight if it's too light than to shed weight if it's too heavy.

Ya if you made an airboat i would just use fiberglass. Carbon fiber is too expensive[]. You can get a sq yrd of fiberglass at autozone for 5$.

Very much so, a airboat can be too lite, the less that they weigh the harder it will become to handle.

Yes and no.

Light flat bottoms will have a tendency to fly with you. On the other hand, with the right engineering....anything is possible.
The RCAA currently has a few members who have a few very light boats that are getting some remarkable speeds out of them. We are talking 3.5 lb boats that are approaching the 50 mph mark, possibly faster, they have not been GPS-ed yet. And these boats are sticking to the water very nicely.
